A new ratiometric fluorescent sensor (LP) based on bicarboxaminoquinoline was designed and synthesized for sequentially recognizing Zn and PPi. In aqueous solution, LP exhibited the ratiometric fluorescence response towards Zn, along with the about 4-folds enhancement of fluorescence quantum yield. Subsequently, the LP-Zn complex displayed the fluorescence recovery upon adding PPi through the displacement strategy. And the LODs of LP and its Zn complex for sensing Zn and PPi were found to be 15 nM and 5.5 nM, respectively. Notably, the reversibility of LP for sequentially sensing Zn and PPi had been employed to construct the INHIBIT logic gate. Moreover, LP and its Zn complex had been successfully utilized for the detection of Zn and PPi in two real water samples and cells imaging.
